i noticed the first sign of gentrification here at the mouth of the end of the world: a cross-walk! so i guess the mega-target-arcology they built is having at least some kind of uplifting effect on the neighborhood. see, the part of flatbush avenue everyone crosses has long been at best quasi-legal. there is a divot in the sidewalk indicating a natural on/off ramp, & even a walk/don't walk sign, but the cross-walks didn't jive with the actual pattern of foot traffic. well, what to my wondering eyes should appear today but the white bars of pedestrian safety!
